Clonezilla is a free, open source disk imaging tool that is loaded with features. While it is a little rough around the edges visually, it is very capable. It supports over a half dozen file systems covering Windows, Linux and Macintosh based computers. If Clonezilla does not support the file system, you can still image the hard drive by doing a sector-by-sector copy.
Clonezilla can be run from a Live CD, USB drives or a network drive and has the ability to either create a single image file, or do a direct copy from one hard drive to another.
